2" venting

The size the listing states. Diameter, material and termination all have to be on your heater maker's approved list; venting is the one part of a gas install nobody should improvise.

Will your heater accept it?

The listing names 2" venting, a horizontal termination and part SP20285.

Only venting on your heater maker's approved list is safe to use. Match the part number in the installation manual before you order.

Great for you if…

Our take

The verdict

The best thing about the Wosijm SP20285 Vent Termination Kit is 2" horizontal venting. No buyer reviews yet, so the Wosijm SP20285 Vent Termination Kit has to win you over on paper. Our main reservation: no word on the exact models it fits. We'd pick it if your heater manual lists this exact vent system; otherwise, put it next to the DiversiTech HVENT2 2" Vent Termination first.

The one thing we'd check first

Before the Wosijm SP20285 Vent Termination Kit ships, check your heater's vent list: it is 2" pipe, and only the vent parts your heater's manual approves are safe.
